 State the rule

Answer :

(i) The direction of a magnetic field produced around a current-carrying conductor can be obtained by using Maxwell's right-hand thumb rule. It states that "if you hold the current carrying wire in your right hand with your thumb pointing in the direction of the magnetic field then the fingers will wrap around the conductor in the direction of the magnetic field lines due to the conductor".
(ii) The direction of the force experienced by a straight conductor carrying current placed in a magnetic field is determined using Fleming's left hand rule. It states that "if you stretch the forefinger, the central finger and the thumb of your left hand mutually perpendicular to each other, the forefinger points in the direction of the magnetic field and the central finger points in the direction of current, and the thumb points in the direction of force acting on the conductor".
(iii) The direction of the current induced in a circuit by changing the magnetic flux due to motion of a conductor is given by Fleming's right hand rule. It states that "if you hold the forefinger, the central finger and the thumb of your right hand mutually perpendicular to each other, the forefinger indicates the direction of the changing field / flux, the thumb indicates the direction of motion of the conductor and the middle finger gives the direction of the induced current". This phenomenon is called electromagnetic induction.
